perf dwarf-aux: Fix build with !HAVE_DWARF_GETLOCATIONS_SUPPORT

The linked fixes commit added an #include "dwarf-aux.h" to disasm.h
which gets picked up in a lot of places. Without
HAVE_DWARF_GETLOCATIONS_SUPPORT the stubs return an errno, so include
errno.h to fix the following build error:

  In file included from util/disasm.h:8,
                 from util/annotate.h:16,
                 from builtin-top.c:23:
  util/dwarf-aux.h: In function 'die_get_var_range':
  util/dwarf-aux.h:183:10: error: 'ENOTSUP' undeclared (first use in this function)
    183 |  return -ENOTSUP;
        |          ^~~~~~~
